The name, however, which is well chofen, has become fo 

 familiar, that I ihall, with a flight alteration, adopt it for the 

 apparatus which I am going to defcribe. Telegraph is a proper 

 name for a machine which defcribes at a diftance. Teklograph^ 

 or contradledly Tellograph, is a proper name for a machine that 

 defcribes words at a diftance. 



Doctor Hooke, to whom every mechanic philofopher muft 

 recur, has written an eflay upon the fubjedl of conveying fwift 

 intelligence, in which he propofes to ufe large wooden letters in 

 fuccefhon. The fiege of Vienna turned his attention to the bu- 

 finefs. This method is more cumbrous than the French Tele- 

 graph, but far lefs liable to error. 



I TRIED it before I had feen Hooke's work in the year 1767 

 in London, and I could diftindtly read letters illuminated with 

 lamps in Hamftead church yard, from the houfe of Mr. Elers 

 in Great Ruffel-ftreet, Bloomfbury, to whom I refer for the date 

 and circumftance — To him and to Mr. E. Delaval, F, R. S. to 

 Mr. Perrot of Harehatch, and to Mr. Woulfe the chemift, I 

 refer for the precedency, which I claim in this invention. In that 

 year I invented the idea of my prefent Tellograph, propofing to 

 make ufe of wind-mill fails inftead of the hands or pointers, 

 which I now employ. Mr. Perrot was fo good as to accompany 

 me more than once to a hill near his houfe to obferve with a 

 telefcope the windmill at Nettlcbed, which places are, I think, 



fixteen
